Dan Strother Oct 2 2004This is my latest, and nicest construct yet. I have deemed it Elysium, since the project just 'came together' and yielded the results I wanted with little fiddling. It's key features include:
Half-bridge of FGH50N6S2D IGBTs
CD4046 based PLL driver electronics (developed by Steve Conner) – this thing is basically immune to upset; I have been able to short the toroid directly to ground with no ill effects.
Adjustable staccato controller – Reduces power consumption and system heating for prolonged runs
No variac required, thanks to the reliability of the PLL and mains-synced turn-on afforded by the staccato controller
Remote dead-man switch operation
Sleek acrylic case
Additional information can be found on my website.

Hi All!
This is my best VTTC.
was born with some pieces of my first VTTC (the first with autotransformer primary) for the occasion of first italian teslathon.
SPECS:
Primary: 52 turns of 2,5 sq-mm cable with PVC insulation wound on 16cm diameter PVC tube, one tap every turn. Secondary: 2230 turns of 0.224mm magnet wire wound on 8.2x50cm PVC tube Feedback: 24 turns of 1 sq-mm, PVC insulated cable wound under the primary Tank cap: 6.75nF 21kV MMC with 100 MKP-HQ capacitors in series-parallel. Power supply: 1,1kVA MOT + level shifter + variac total power: 1520W true power ( measured by double coil wattmeter, filament power included ) sparklengt: 1-40cm, adjustable note: fully adjustable via autotransformer primary for maximum voltage or current in every load conditions
